A cell aka battery.
A electric current produces a magnetic field
Either the cell e.g. a battery, if one is included in the circuit. Or a generator such as a dynamo
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.

A cell aka battery.
A electric current produces a magnetic field
A chemical cell or strings of cells called a battery.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.

A changing magnetic field produces an electric current, so yes. This is true.
In most cases, chemical energy stored in the battery produces the electric current. Rechargeable batteries are capable of taking electric currents and using them to reverse the chemical reactions, thus gaining more chemical energy that can be used readily.
